Lovely work as always - clearly missed it first time around. Really like the way you've got the res flush with the top.
If you can machine an EK res port to take standard fittings, why the *$%£ can't they just make them that way in the first place?! Much more sensible solution.
EVGA logo looks great on the front slightly embossed. Not sure what the layers behind it are like but for a future project, backlit would look good. The Aquaero has an RGB LED header which takes a single common cathode RGB LED - the more common type of 5mm through-hole (dome with legs) style. Would depend on whether you can get an LED in there neatly and still diffuse it nicely into all the letters - I suspect not as a retrofit but could be worth considering if you're doing another.
FYI: Farbwerk's can take 4 channels of RBG LED strips but if you want 5mm dome stlye LEDs, it can be done provided you get common anode (the rare type only found from China it seems) RGB LEDs and solder a bucket load of resistors on. If your CNC can go accurate enough, you could CNC a PCB from copper-clad board and then solder the LEDs through-hole (or get surface mount SMDs if you can find common anode) for support and to make the wiring easier.
